- The process for manufacturing a display panel in the related art will be described hereinafter at first.
-
FIG. 1 shows the process for manufacturing the display panel in the related art. As shown inFIG. 1 , the process for manufacturing the display panel may include the following steps. - Step (a): providing a first substrate 1. The first substrate 1 may be an array substrate or a color filter substrate.
- Step (b): applying a
sealant 2 to the first substrate 1 at a predetermined position. To be specific, thesealant 2 may be applied to a periphery of the first substrate 1, i.e., thesealant 2 may be applied in such a manner as to form an approximately square or rectangular shape. Of course, a shape of thesealant 2 may be selected in accordance with the practical need. - Step (c): providing a
second substrate 4. When the first substrate 1 is an array substrate, thesecond substrate 4 may be a color filter substrate, and when the first substrate 1 is a color filter substrate, thesecond substrate 4 may be an array substrate. Then,liquid crystals 3 may be dripped onto thesecond substrate 4 in a One Drop Fill (ODF) manner. - Step (d): turning over the first substrate 1, and attaching the first substrate 1 to the
second substrate 4 to form a cell. At this time, thesecond substrate 4 may be adhered to the first substrate 1 through thesealant 2. - Step (e): irradiating the
sealant 2 with ultraviolet light after the cell formation (in a direction as indicated by arrows inFIG. 1 ) so as to pre-cure thesealant 2, and then thermosetting thesealant 2 to acquire the display panel. - It is found that, after the cell formation and before the pre-curing of the sealant with the ultraviolet light, such defects as the sealant being pierced through by liquid crystals, pollution of liquid crystals, and afterimages may occur, and thereby the display quality of the display panel may be adversely affected. In addition, moisture may enter the sealant, resulting in corrosion of lines on the array substrate and thereby display abnormalities.
- The sealant is located adjacent to a display region, and after the cell formation, the liquid crystals in a liquid crystal layer may diffuse outwardly. When the liquid crystals are in contact with the sealant which has not been cured, the above-mentioned defects such as the sealant being pierced through by the liquid crystals, the pollution of liquid crystals, and the afterimages may occur, and thereby the display quality of the display panel may be adversely affected. In addition, moisture may enter the sealant, resulting in corrosion of wires on the array substrate and thereby display abnormalities.
- In a word, in the related art, when the liquid crystals are in contact with the sealant which has not been cured, the display quality of the liquid crystal display panel may be adversely affected, and thereby the display abnormalities may occur subsequently.
- An object of the present disclosure is to provide a display device, a manufacturing method thereof and a sealant, so as to solve the above-mentioned problem.
- Technical solutions of the present disclosure will be described in detailed in conjunction with the drawings as follows.
- The present disclosure provides in some embodiments a display device which, as shown in
FIGS. 2 and 3 , includes a first substrate 1, asecond substrate 4 arranged opposite to the first substrate 1, and asealant 2 configured to seal the first substrate 1 and thesecond substrate 4. Thesealant 3 includes a colloid and a plurality ofmagnetic particles 20 arranged in the colloid. - As shown in
FIG. 4 , eachmagnetic particle 20 may include a supportingcore 21 and amagnetic layer 22 enclosing an outer surface of the supportingcore 21. A magnetic field force pointing toward the first substrate 1 or thesecond substrate 4 may be applied to eachmagnetic particle 20 under the effect of an external magnetic field. In addition, when themagnetic material 22 is made of nickel which is electrically conductive, aninsulation layer 23 may also enclose the outer surface of themagnetic layer 22, so as to prevent a wire on an array substrate from being short-circuited due to the existence of nickel. - The display device may be a display panel, and at this time, it may further include
liquid crystals 3 arranged between the first substrate 1 and thesecond substrate 4. The first substrate 1 may be an array substrate or a color filter substrate. When the first substrate 1 is an array substrate, thesecond substrate 4 may be a color filter substrate, and when the first substrate 1 is a color filter substrate, thesecond substrate 4 may be an array substrate. A structure of each of the first substrate 1 and thesecond substrate 4 is known in the art and thus will not be particularly defined herein.FIG. 3 is a planar view of the display device. - According to the display device in the embodiments of the present disclosure, the plurality of
magnetic particles 20 may be arranged in thesealant 2, and themagnetic layer 22 may enclose the outer surface of the supportingcore 21 of eachmagnetic particle 20. When the external magnetic field is applied from one side of the first substrate 1 or thesecond substrate 4 toward thesealant 2, the magnetic field force pointing toward the first substrate 1 or thesecond substrate 4 may be applied to eachmagnetic particle 20, so as to increase a friction force between the magnetic particle and the first substrate 1 or thesecond substrate 4, thereby to weaken the flow of thesealant 2. As a result, it is able to prevent the sealant from being pierced through by the liquid crystals, prevent the liquid crystals from being polluted, and prevent the occurrence of after images, thereby to improve the display quality of the display device. - As shown in
FIG. 5 , in order to apply the magnetic field force pointing toward the first substrate 1 or thesecond substrate 4 to eachmagnetic particle 20 under the effect of the external magnetic field, the display device may further include a magneticfield generation unit 51 arranged at a side of the first substrate 1 and configured to generate a magnetic field pointing toward the first substrate 1 between the first substrate 1 and thesecond substrate 4. A position of the magnetic field may correspond to a position of the sealant. In a possible embodiment of the present disclosure, the magneticfield generation unit 51 may also be arranged at a side of thesecond substrate 4 and configured to generate the magnetic field pointing toward thesecond substrate 4 between the first substrate 1 and thesecond substrate 4. At this time, a position of the magnetic field may also correspond to a position of thesealant 2. - In the embodiments of the present disclosure, after the first substrate 1 is arranged opposite to the
second substrate 4 to form a cell and before thesealant 2 is cured, the first substrate 1 and thesecond substrate 4 may be moved into the magneticfield generation unit 51. The magneticfield generation unit 51 may generate the magnetic field pointing toward the first substrate 1 or thesecond substrate 4 between the first substrate 1 and thesecond substrate 4 and the position of the magnetic field may correspond to the position of thesealant 4. At this time, the magnetic field force pointing toward the first substrate 1 or thesecond substrate 4 may be applied to eachmagnetic particle 20 in thesealant 2, so as to increase the friction force between themagnetic particle 20 and the first substrate 1 or thesecond substrate 4, thereby to weaken the flow of thesealant 2. As a result, it is able to prevent the sealant from being pierced through by the liquid crystals, prevent the liquid crystals from being polluted, and prevent the occurrence of after images, thereby to improve the display quality of the display device. - To be specific, as shown in
FIGS. 5 and 6 , the magneticfield generation unit 51 may include aconductive loop 6, and anelectromagnetic conversion member 6 connected to theconductive loop 6 and configured to apply the magnetic field to theconductive loop 6. Theconductive loop 6 may be arranged at a side of the first substrate 1 away from thesecond substrate 4, and extend along thesealant 2. In a possible embodiment of the present disclosure, theconductive loop 6 may be arranged at a side of thesecond substrate 4 away from the first substrate 1, and extend along thesealant 2. - Specifically, as shown in
FIGS. 5 and 6 , the electromagnetic conversion member may include awire 71, apower source 72 and acoil 73. Thewire 71 may be connected to theconductive loop 6. Thecoil 73 may be wound on thewire 71, with one end being connected to a positive pole of thepower source 72 and the other end being connected to a negative pole of thepower source 72. - Of course, apart from the coil, the magnetic field may be generated by the magnetic field generation unit in any other forms.
- In a possible embodiment of the present disclosure, an orthogonal projection of the
conductive loop 6 onto the first substrate may coincide with an orthogonal projection of thesealant 2 onto the first substrate, so that the magnetic field generated by thecoil 73 along theconductive loop 6 is applied to thesealant 2 in a direction perpendicular to the first substrate 1 or thesecond substrate 4. - In order to apply the magnetic field force to each
magnetic particle 20 in thesealant 2 in a more concentrated manner and further increase the friction force, a width of the conductive loop may be smaller than or equal to a width of thesealant 2 in a first direction (e.g., a horizontal direction of the first substrate 1). - In order to describe the embodiments of the present disclosure clearly, the display device will be described hereinafter in more details.
- Here, the first substrate 1 may be an array substrate, the
second substrate 4 may be a color filter substrate, and the magnetic field generation unit may be arranged at a side of the first substrate 1. - As shown in
FIGS. 5 and 6 , thesealant 2 may be applied to the first substrate 1 at a predetermined position. For example, thesealant 2 may be applied in such a manner as to form a rectangular shape. Of course, a shape of thesealant 2 may also be selected in accordance with the practical need. The magneticfield generation unit 51 may be arranged at a side of the first substrate 1 away from thesecond substrate 4. During the implementation, an orthogonal projection of theconductive loop 6 of the magneticfield generation unit 51 onto the first substrate may coincide with an orthogonal projection of thesealant 2 onto the first substrate. Thewire 71 of the electromagnetic conversion member 7 may be connected to theconductive loop 6. Thecoil 73 may be wound onto thewire 71, with one end being connected to the positive pole of thepower source 72 and the other end being connected to the negative pole of thepower source 72. An intensity of the magnetic field generated by the electromagnetic conversion member 7 may be calculated through the following equation: H=NI/Le, where H represents the intensity of the magnetic field generated by the electromagnetic conversion member 7 and has a unit of ampere per meter (A/m), N represents the number of turns of thecoil 73, I represents a current flowing through thecoil 73 and has a unit of ampere (A), and L2 represents a valid magnetic path length of theconductive loop 6 and has a unit of meter (m). Through the electromagnetic conversion member 7, it is able to convert an electric field into the magnetic field. - After the first substrate 1 is arranged opposite to the
second substrate 4 to form a cell and before thesealant 2 is cured with the ultraviolet light, as shown inFIGS. 5, 6 and 7 , thepower source 72 may be enabled, so as to apply a current to thecoil 73 and enable thecoil 73 to form an energized solenoid. The magnetic field may be generated by the energizedcoil 73 and transmitted to theconductive loop 6 via thewire 71, so as to generate the magnetic field above theconductive loop 6 and perpendicular to the first substrate 1. When the width of the conductive loop is smaller than the width of thesealant 2 in the first direction (e.g., the horizontal direction of the first substrate 1), the magnetic field force pointing toward theconductive loop 6 may be applied to each magnetic particle in thesealant 2 under the effect of the magnetic field (inFIG. 6 , a direction of a magnetic field line is indicated by each arrow), so as to increase the friction force between thesealant 2 and the first substrate 1. After thesealant 2 has been cured, the first substrate 1 and thesecond substrate 2 may be moved out of the magnetic field generation unit. - When the
power source 72 is enabled, a downward magnetic field force may be applied to eachmagnetic particle 20 in thesealant 2, as shown inFIGS. 6 and 7 (a direction of a magnetic field line is indicated by each arrow), so as to increase the friction force between themagnetic particle 20 and the first substrate 1, thereby to further weaken the flow of thesealant 2. As a result, it is able to prevent theliquid crystals 3 from being mixed with thesealant 2, thereby to prevent the sealant from being pierced through by the liquid crystals. - As mentioned above, the magnetic field generated by the magnetic field generation unit may take effect during the curing of the
sealant 2. However, the magnetic field may also be adopted to correct a position of thesealant 2 when thesealant 2 is applied at a wrong position. During the implementation, apart from the defects caused when thesealant 2 is pieced through by the liquid crystals, there may exist the other defects when thesealant 2 is applied at the wrong position. For example, when thesealant 2 is applied at the wrong position, a circuit of the display panel may be exposed to be outside, and thereby may easily be oxidized, corroded or etc. At this time, the position of thesealant 2 may be adjusted to a predetermined position under the effect of the magnetic field generated by the magnetic field generation unit on themagnetic particles 20. - The present disclosure further provides in some embodiments a sealant which includes a colloid and a plurality of
magnetic particles 20 arranged in the colloid. Eachmagnetic particle 20 includes a supportingcore 21 and amagnetic layer 22 enclosing an outer surface of the supportingcore 21.FIG. 4 shows the structure of themagnetic particle 20. - When the
sealant 2 is applied onto a substrate and a magnetic field is applied to thesealant 2, a magnetic field force pointing toward the substrate may be applied to eachmagnetic particle 20, so as to increase a friction force between themagnetic particle 20 and the substrate. As a result, it is able to weaken the flow of thesealant 2, thereby to locate the sealant at a desired position in a better manner. - In a possible embodiment of the present disclosure, as shown in
FIG. 4 , thesealant 2 may further include aninsulation layer 23 enclosing the outer surface of themagnetic layer 22, so as to protect the supportingcore 21 and themagnetic layer 22, and provide an insulation effect on electric signals. - Illustratively but non-restrictively, the supporting
core 21 may be a silicon ball, and themagnetic layer 22 may be made of nickel or ferroferric oxide. The supportingcore 21 may be arranged in a manner similar to that known in the art so as to support the first substrate and the second substrate, which will thus not be particularly defined herein. - A process for manufacturing the
magnetic layer 22 and theinsulation layer 23 will be described hereinafter in more details. - The
magnetic layer 22 may be deposited as follows. Nanoscale magnetic metal particles (e.g., nickel (Ni) or ferroferric oxide (Fe3O4)) may be deposited onto the outer surface of the supportingcore 21 through an electroless plating process. Here, the nanoscale Ni particles and the silicon ball will be taken as an example. At first, a solution mixed with silicon balls maybe prepared. Next, 10 ml of a 0.8 mol/L nickel chloride (NiCl2) solution, 13.6 ml of absolute ethyl alcohol and 6.7 ml of distilled water may be added into the solution mixed with the silicon balls, and a resultant mixture may be stirred uniformly in a 100 ml beaker. Next, a temperature-constant magnetic stirrer capable of displaying readings may be placed into the beaker, and the mixture may be heated while being stirred. During the heating and stirring, a 5 mol/L NaOH solution may be added so as to adjust a pH value of the resultant mixture to about 14. After the adjustment of the pH value, about 20 ml of hydrazine hydrate may be added drop by drop, and a resultant mixture may be heated to 50° C. and maintain for about 0.5 h. Then, a resultant sample may be washed and dried at a temperature of 50° C. for 2 h in a vacuum oven, so as to acquire the silicon ball with a magnetic Ni layer being deposited onto its outer surface. The magnetic particles having different magnetic properties may be acquired through the adjustment of a concentration of the NiCl2 solution. - In another embodiment, the
insulation layer 23 may be deposited as follows. A matrix including the magnetic particles acquired as mentioned above may be subjected to ultrasonic dispersion in an ethanol solution, and added into a dopamine solution having a centration of 0.5 g/L to 4 g/L and a pH value of 6.0 to 10.0. Next, a resultant mixture may be stirred for 2 h to 48 h at a rate of 30 revolutions per minute (rpm) to 100 rpm, so that dopamine in the dopamine solution is capable of being deposited onto the outer surface of themagnetic layer 22, thereby to acquire themagnetic particle 20 as shown inFIG. 4 . - The present disclosure further provides in some embodiments a method for manufacturing the above-mentioned display device which, as shown in
FIG. 8 , includes: - S101 of applying a sealant onto a first substrate or a second substrate, and arranging the first substrate opposite to the second substrate to form a cell;
- S102 of placing the first substrate and the second substrate in an external magnetic field so as to apply a magnetic field force pointing toward the first substrate or the second substrate to each magnetic particle, and curing the sealant; and
- S103 of moving the first substrate and the second substrate out of the external magnetic field after the sealant has been cured.
- During the implementation, S101 of applying the sealant onto the first substrate or the second substrate and arranging the first substrate opposite to the second substrate to form a cell is similar to that known in the art, and thus will not be particularly defined herein.
- In addition, S102 of curing the sealant is similar to that known in the art, and thus will not be particularly defined herein. In a word, conventional processes may be adopted for the application and the curing of the sealant, so the manufacture cost may not increase.
- The present disclosure has the following beneficial effects.
- Firstly, when the sealant is applied onto a substrate and a magnetic field is applied to the sealant, the magnetic field force pointing toward the substrate may be applied to each magnetic particle, so as to increase the friction force between the magnetic particle and the substrate. As a result, it is able to weaken the flow of the sealant, thereby to locate the sealant at a desired position in a better manner.
- Secondly, the plurality of magnetic particles may be arranged in the sealant, and the magnetic layer may enclose the outer surface of the supporting core of each magnetic particle. When the external magnetic field is applied from one side of the first substrate 1 or the second substrate toward the sealant, the magnetic field force pointing toward the first substrate or the second substrate may be applied to each magnetic particle, so as to increase a friction force between the magnetic particle and the first substrate or the second substrate, thereby to weaken the flow of the sealant. As a result, it is able to prevent the sealant from being pierced through by the liquid crystals, prevent the liquid crystals from being polluted, and prevent the occurrence of after images, thereby to improve the display quality of the display device.
- Thirdly, after the first substrate is arranged opposite to the second substrate to form a cell and before the sealant is cured, the first substrate and the second substrate may be moved into the external magnetic field, and the magnetic field force pointing toward the first substrate or the second substrate may be applied to each magnetic particle in the sealant, so as to increase the friction force between the magnetic particle and the first substrate or the second substrate, thereby to weaken the flow of the sealant. As a result, it is able to prevent the sealant from being pierced through by the liquid crystals, prevent the liquid crystals from being polluted, and prevent the occurrence of after images, thereby to improve the display quality of the display device.
- The above embodiments are for illustrative purposes only, but the present disclosure is not limited thereto. Obviously, a person skilled in the art may make further modifications and improvements without departing from the spirit of the present disclosure, and these modifications and improvements shall also fall within the scope of the present disclosure.
